In the divide-and-conquer approach, what is the primary role of the 'conquer' step? Please be aware that there will be point deductions for incorrect answers. To reduce the problem size in each iteration. To solve each of the smaller subproblems, typically recursively. To combine the solutions of the subproblems. To apply a greedy strategy for quick solution finding. To optimize the solution for each subproblem. To divide the problem into smaller subproblems.

- 3. Early one morning you go to fill up your steel fuel container with gasoline that has a volume of 20 L. You fill it all the way up when the temperature is 0°C. Later that day, the temperature rises to 20°C. How much gasoline spills out of your container? The volume coefficients of expansion of steel and gasoline are β₁ = 3.3 x 10⁻⁵ (°C)⁻¹ and β₁ = 9.6 x 10⁻⁴ (°C)⁻¹, respectively. - V=20L - T=0°C - T=20°C - AV=BVAT - △V=(9.6×10⁻⁴)(20)(20) - AV=0.0384 - A. 0.40 L - B. 0.038 L - C. 0.37 L - D. 0.013 L - E. None, the volume of steel expands more than gasoline. - 4. A balloon of volume V contains an ideal gas at an initial pressure P. First, the balloon expands isobarically by doubling the number of moles of gas for a volume of 2V. The pressure then decreases isovolumetrically to 0.25P. Which of the following statements about the initial and final rms speeds of the molecules in the balloon is correct? - A. The final rms speed is 0.5 times the initial rms speed. - B. The final rms speed is 2 times the initial rms speed. - C. The initial and final rms speeds are the same. - D. The final rms speed is 0.25 times the initial rms speed. - E. The final rms speed is 4 times the initial rms speed.

In a shell-and-tube heat exchanger, hot water is pumped through the pipe at a rate of 3,000 [kg/hr] and cooled from 55 [℃] to 40 [℃]. Meanwhile, on the outside, coolant flows at a speed of 5,000 [kg/hr] at 25 [℃]. Find the amount of heat transfer through the heat exchanger. Put 1,800 [kg] of 110 [℃] oil (specific heat 0.45 kcal/kg℃) into the inner tube of a double pipe heat exchanger and take it out when the temperature is 45 [℃]. Add water (countercurrent) to the pipe wall at 20[℃] and take it out at 50[℃]. If the inner diameter of the pipe is 36 [mm] and the overall heat transfer coefficient based on the inner area is 500 [kcal/m^2hr℃], what is the required heat transfer area [m^2]?
